Long-term evaluation of air sensor technology under ambient conditions in Denver, Colorado.

ABSTRACT: Air pollution sensors are quickly proliferating for use in a wide variety of applications, with a low price point that supports use in high-density networks, citizen science, and individual consumer use. This emerging technology motivates the assessment under real-world conditions, including varying pollution levels and environmental conditions. A seven-month, systematic field evaluation of low-cost air pollution sensors was performed in Denver, Colorado, over 2015-2016; the location was chosen to evaluate the sensors in a high-altitude, cool, and dry climate. A suite of particulate matter (PM), ozone (O₃), and nitrogen dioxide (NO₂) sensors were deployed in triplicate and were collocated with federal equivalent method (FEM) monitors at an urban regulatory site.
